1 Claim. (Cl. 189-86) My invention relates to panels for use in thebuilding art.

Many types of bungalows and other dwellings have their outer wallsfinished with clapboard or feather edge which gives a pleasingappearance to the exterior of the building; However this type of outerwall, when constructed of wood, has its disadvantages, in that unless itis painted every few years, it soon begins to look shabby and the oldpaint weathers and scales off exposing the wood work to the vicissitudesof the elements, and deterioration or rot sets in.

The use of dressed wood is in the first instance, costly, and when it isconsidered that the lifetime of timber is relatively short being exposedto termites and other pests and the cost of periodic painting and labourinvolved is high, it was apparent to me that other and more permanenttypes of finishing could be used, which would have long life anddurability and possess all the aesthetic features of known sidings andfinishings.

Consequently I have come to the conclusion that metallic siding or anequivalent, such as Fiberglas or other synthetic materials, would lenditself to building construction, and to this end I have invented ametallic or equivalent panelling which may be used to constitute theouter Walls of a building and to give a useful and attractive finishthereto.

The panelling which I have invented is so constructed that insulatingmaterial can be positioned in the interior of the panel, so assuring asuitable temperature in a building all the year round.

Moreover the type of panel which I have invented can be used as anacoustical ceiling by merely providing a plurality of apertures in theouter wall of the panel and placing in the interior of the panel a padof mineral wool or other acoustical material.

.The advantages of the use of metallic or equivalent panelling inbuilding construction is obvious, and what I am particularly interestedin is to construct the panels so that the abutting end walls. of thepanels may be.

securely joined and locked in position.

One of the objects of my invention is to provide a building panel whichwhile strong and durable, may be fabricated with pleasing lines, soadding to the aesthetic beauty of a building finished with such panels.

Another object is to retain the assembled panels in- Other objects willbe made clear as the specification I develops.

So that the nature of my invention will be clearly understood, I haveillustrated two embodiments of the same'which I shall describe indetail, but I wish it to be understood that I do not limit my inventionto these specific forms, but reserve the right to modify the same withinthe scope of my appended claim.

Like characters of reference refer to like parts in the several figures.

Referring to Figures 1 to 8 inclusive of the drawings, A represents apart of a panel blank, the upper and lower ends of which are identical,so that the shape of one end will be described in detail, but thereference characters Will be applied to both ends wherever possible.

The length of the panels will be such as are required for the desiredpurpose, and the panels will be cut from strips of aluminium or othersuitable material of the desired Width so that there will be a minimumof wastage in the cutting operations.

The end of each panel blank A is formed at its upper and lower edge witha rectangular projecting portion 10, the outer marginal portions ofwhich are provided with orifices 11. The dotted lines 7 and 8 shown onthe projecting rectangular portion 10 are for a purpose which will bereferred to hereafter.

By reference to Figure 2 it will be seen that the left hand marginalportion 12 is cut away and angularly disposed as shown at 13 towards therectangular projection 10, and that the part of this marginal portionadjacent the projecting rectangular portion 10 is provided with a 0 slitor cut 14 which extends to the root of the rectangular projection 10.

This marginal portion 12 of the blank A is shown,

with two dotted lines, 15 and 9, on which the marginal portion ispartially folded to form a V-shaped flange 16 which constitutes a malemember B of an interlocking joint between adjacent panels A.

The opposite or right hand marginal portion 17 of the panel blank A isformed with a portion of its upper edge 18 angularly disposed towardsthe rectangular portion 16, and is formed with a slit or cut 19 whichextends to the root of the rectangular projection 10, the slit 19 being.of the same depth as the slit 14 on the left hand portion of the panel.From the lower outer end of the angular edge 18 an upper edge 20 of themarginal portion 17 extends outwardly at right angles to the verticaledge of the panel blank A, and adjacent the marginal portion of theblank a plurality of orifices 21 are provided.

The right hand marginal portion 17 of the panel A is shown with fivedotted lines 22, 23, 24, 25 and 25a, and along these lines the righthand marginal portion 17 is folded to form a double bend which simulatesthe letter N, and constitutes a female member C of the interlockingjoint between adjacent panels.

As previously stated the lower end of the panel blank A is similar inall respects to the upper end which is described in detail above.

When the rectangular blank, which for the purposes of description isformed of an aluminum sheet, is cut away or shaped as above described,then the marginal portion 12 on the left hand side of the blank ispartially folded on the'line 9, and a further folding operation isperformed in the opposite direction on the line 15, so forming aV-shaped locking portion =16 of the male joint B, and the V-shapedportion extends from the top to the bottom of the panel blank A.

That part of the upper edge 13 of the marginal portion 12 which isprovided with the slit 14 now underlies the plane of the blank A and isfolded inwardly beneath the blank to form a lug 26 as shown in Figure 3.The right hand marginal portion 17 of the panel blank A is now foldeddownwardly on the line 22 and a second folding operation is made on thedotted line 24 as clearly shown in Figure 6.

A third folding is made along the line 23 so that this fold underliesthe lateral end wall of the panel A, whereupon a fourth foldingoperation is made on the line 25 to form the female part C of the jointand the marginal portion on the right hand of the panel blank A projectsoutwardly forming a lateral flange 27, which is broken upwardly on theline 25a to form the inclined side wall 27a of a water trough.

The portion bounded by the slit 19 and the inclined edge 18 of themarginal portion 17 underlies the plane of the plane blank A, and isfolded inwardly thereunder to form a lug 28 as shown in Figure 3.

The rectangular upper and lower portions of the panel blank A are foldeddownwardly on the dotted line 8 at right angles to the plane of thepanel blank, and the outer margin of the rectangular projecting portion10 is then folded outwardly on the dotted line '7 to form a flange 6 asshown in Figure 1. It will be clear that lugs 26 and 28 bridge thespaces between the lateral walls of the panel and the upper and lowerend walls of the panel.

This folding of the marginal portions of the panel blank A forms apanel, the under or inner side of which is dished, and adapted toreceive and retain therein, a pad of rock wool or other suitableinsulating material. The flanges 27 and 6 lie in the same plane which isparallel to the outer face of the panel A.

A plurality of these panels may be used to complete or finish the outerwalls of a dwelling or other building, and one panel is secured to theouter rough lumber siding of the building by nails which are driventhrough the orifices 11 and 21 into the woodwork.

The next panel is now positioned adjacent to the first fixed panel andinclined outwardly at an angle thereto so that the lip of the V-shapedgroove 16 of the male 4 I portion B of the joint is inserted between theflange 27 and the folded female portion of the joint C.

The second panel is now rotated towards the Wall of the building onwhich the panels are being mounted, and this causes the male portion Bof the joint to engage the groove of the female portion C of the joint,and the second panel is now in alignment with the first panel and islocked end to end in alignment therewith, whereupon the second panel issecured to the woodwork of the frame of the building by nails.

The assembly of the adjacent parts of the panels will be understood byreference to Figure 4 and it will be clear that the interlocking ofadjacent panels is positive so that displacement of the panels is notpossible and the panels are held in alignment. This operation isrepeated with the assembly of each row of panels until the outer wallsof the building are covered.

In the event of unexpected leakage of water taking place between themale and female portions B and C of the joint, such water would becaught in the trough formed by the flange 27 and the broken up inclinededge 27a, and the water drained oif.

Referring now to Figure 9, the upper portion of a panel blank A1 isillustrated, but it will be understood that the lower edge portion ofthe blank is of similar construction but oppositely disposed to theupper portion, and it is not thought necessary to illustrate the panelblank in full.

In Figures 9 to 12 the panel blank A1 is formed on its upper edge andsimilarly on its lower edge with a projecting rectangular portion 30,and the left hand marginal portion 31 of the blank has its upper andlower edges angularly disposed relatively to the adjacent lateral edgeof the rectangular portion 30 as shown at 32.

A dotted line 33 is shown on the panel blank A1 in Figure 9 and themarginal portion 31 of the panel blank is partially folded on this linedownwardly and angularly relatively to the face of the panel blank, andthis folded portion 31 underlies the panel blank and constitutes themale member D of a joint between adjacent panels as shown in Figure 11.

The marginal portion 34 on the right hand side of the panel blank A1 isformed with upper and lower edges extending from the root of therectangular projection 30 and at right angles to the lateral edge of therectangular projection, and the edges 35 are each provided intermediateof their length with a V-shaped notch 36.

Dotted lines 37, 38, 39 and 40 are shown on the face of the panel blankA1, and the line 37 extends between the right hand lateral edge of theupper rectangular projection 30 to the right hand lateral edge on thecorresponding projection on the lower end of the panel blank. The lines38, 39 and 40 extend between the ends and center of the V-shaped notch36 on the upper edge 35 to the corresponding V-shaped notch on the edgeat the lower end of the panel blank.

The right hand marginal portion 34 of the panel blank A1 is now foldedalong the lines 37, 38, 39 and 40 to form a female member E and aprojecting flange 41 of a joint between adjacent panels as shown inFigure 11.

The folds formed along the lines 37, .38 and 39 constitute a doublefold, and simulate a letter N reversed, and the extreme marginal portionbetween the line 40 and the lateral edge of the panel blank A1constitute the flange 41 which is provided with orifices 42.

The rectangular projecting portions 30 on the upper and lower ends ofthe panel blank A1 have two dotted lines 43 and 44, and the projectingportion 30 is folded downwardly at right angles to the plane of theouter face of the panel blank A1 along the line 43, and a second fold ismade along the line 44 at right angles to the first fold, to constitutea flange 45 which is provided with orifices 46. The flanges 41 and .5lie in the same plane which is parallel with the upper face of the panelblank In assembling these panels on the outer walls of a building, oneof the panels A1 is located in the desired position, and nails aredriven through the orifices 46 and 42 in the flanges 45 and 41 into thewooden siding of the building firmly securing this first panel inposition.

-A second panel A1 is then positioned as shown in Figure 11, slightlyspaced from the first panel A1, with the male member D in alignment withthe female member E of the panel joint, and the second panel is pressedtowards the wooden siding of the building so that the male memberfrictionally engages with, and is embraced by the female member E of thejoint. In this position the flanges 45 and 41 of the second panel A1engage the outer face of the wooden siding of the building to which thesecond panel A1 is secured by nails driven through the orifices 46 and42 of the flanges 45 and 41 into the wooden siding. The two assembledpanels are shown in Figure 12.

The above operation is repeated with other panels until the outer wallof the building is completely covered by the panels.

Insulating material in the desired form, such as pads, may be readilyplaced in the interior of each panel before assembly.

The embodiments of the invention in which an exclusive property orprivilege is claimed are defined as follows:

I claim:

A rectangular building panel having upper and lower depending end walls,flanges extending outwardly from the lower edges of the end walls, adownwardly and outwardly inclined side wall having an upwardly andoutwardly inclined portion forming the male member of a joint, a secondside wall inclined downwardly and outwardly from the panel and reverselybent inwardly and upwardly and then downwardly to form a double foldwith the folds in an inclined plane and spread apart constituting thefemale member of. the joint, the lower end of the second side wallterminating below the folds in an outwardly extending flange having itsouter edge turned upwardly to form a trough.
